ADJUSTABLE BUTTON AND BIJTTONHOLE.

SPECIFICATION forming part of Letters Patent N0. 488,090, dated December 13, 1892.

Application tiled .Tune 30, 1892. Serial No. 438,591. (No model.)

To a/ZZ whom t may concern.-

Be it known that I, FREDERICK S. RUDGE, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Adjustable Button and Buttonhole, of which the following is a speciiication.

My invention relates to an improvement in an adjustable button and buttonhole having two sets of disks attachable to separate portions of the desired object, each set of disks being also capable of adjustable connection with the other set of disks.

The objects of my invention are to provide an adjustable but-ton and buttonhole which shall be readily attached to a desired article and hold the separate portions thereof securely together when buttoned, but which is also readily unbuttoned and detached, an adjustable button and buttonhole which shall not require a sewed buttonhole, an adjustable button and buttonhole which shall not tear out of the cloth to which it is attached, an adj ustable button and buttonhole in whichv the use of pins for attach ment is obviated, and an adjustable button and buttonhole capable of sustaining great and continuouswear.l I

accomplish these objects by the device illustrated in the accompanying drawings,in which similar letters are used to designate similar parts throughout. f I

Figure lis a central longitudinal section of my adjustablebutton and buttonhole, showing the disks C D and E G attached to respective portions of a garment A B, the disksv C D being fitted over the spring-post F of the disks E G. Fig. 2 is a central longitudinal section of my adjustable button and buttonhole detached from a garment, the disks C D being partly over the spring-post F of the disks E G. Fig. 3 is aview of the upper side of the disk D and the spring-post F. Fig. 4. is a view of the upper side of the disk E and spring-post F.

My adjustable button and buttonhole, which is made of brass or other suitable inaterial, is provided with disks C D and E G. The disk C has in its center, upon its upper side, a threaded shank C', the interior of the shank C being smooth. The disk D has in its center a threaded boring adapted to engage with the thread of the shank C of the disk C. The disk E has upon its upper side a post F, provided with a split or opening f. The post F is adapted to tit snugly the interior of the shank C ot the disk C, the head of the post F being of greaterl diameter than the lower portion otl the post, but being adapted by compression of the split f to be inserted into the shank C', Fig. 2. Upon the under side of the disk E is a threaded projection e. The disk G has in its center a threaded boring adapted to engage with the projection e of the disk E.

The operation of my adjustable button and buttonhole is as follows: The disk D is unscrewed from the shank C of the disk C. The

disk G is unscrewed from the projection e of the disk E. A hole is made through the desired cloth A to receive the shank C of the disk C, and the disk D screwed tightly over the shank C', so that the cloth A is compressed between the two disks C D, Fig-l. A hole ismade through the desired cloth B to receive the projection e of the disk E, and the disk G is screwed tightly over the projection e, so that the cloth B is compressed between the two disks E G, Fig. l. It is thus seen that so much of the cloth A B is compressed between the surfaces of the disks C D and E G as to prevent the button and buttonhole from tearing out of the cloth to which it is attached. The spring-post F is inserted in the shank C and pushed through the shank C, the spreading head of the spring-post thus holding the two portions of the adjustable button and buttonhole and the desired cloth firmly together, Fig. l.

The slight concavity of the bottom ot' the disk O (shown in the drawings) is merely intended to act as somewhat of a guide for the spring-post F when it is inserted in the shank C and is not essential to the construction.

The openings shown near the edges of the disks D G are forV the insertion of a suitable key to screw the disk D upon the shank C and the disk G upon the projection e and are not essential to the construction.

Having fully described my invention, what I claim, and desire to protectby Letters Patent, is-

The combination, with the' disks D G, of the disk C, having shank C', and the disk E, having springpost F, and projection e, substantially as described, and as and for the purposes set forth.

FREDERICK S. RUDGE.
